What, after all, is there to say? We tell our friend that the theatre is a place where people come and go, obsessively it would seem, through the same exposed rooms and spaces (they have been coming and going across the same exposed space of the Royal Court in London for decades), and where they perform various harmless and inconsequential actions: a bit of wandering around, some waving of the arms, some standing up and sitting down, and playing it all up as they do so, often getting remarkably excited. It is a place too, we tell our friend, where every action that is performed appears planned out or scripted in advance, at least to an extent. This produces a strange effect, we say, in that the people who are coming and going across the space - let's call them the actors - seem to have all the freedom in the world to do whatever they like, even the freedom not to do anything at all. But at the same time they seem constrained, as if all their choices are somehow being made for them somewhere else, and as if every move they make is basically a renewed attempt to deal with this peculiar situation.
